Email click-through rate

Divide unique clicks by the number of emails delivered, then multiply by 100. Where open rate shows whether the subject line worked, click-through rate (CTR) shows whether the email itself did.

CTR = (Unique clicks ÷ Emails delivered) × 100

Sent: 10,000   Delivered: 9,800   Unique clicks: 294
CTR = (294 ÷ 9,800) × 100 = 3.0%

Click-to-open rate (CTOR) divides the same clicks by unique opens instead.

CTOR = (Unique clicks ÷ Unique opens) × 100

Unique opens: 2,450   Unique clicks: 294
CTOR = (294 ÷ 2,450) × 100 = 12.0%

• CTA design

  Placement, design and copy all matter. Clear, prominent, action-led CTAs beat “Click here”.

• Relevance

  Targeted, personalized content gets 2-3x the CTR of generic blasts.

• Value proposition

  Exclusive content, limited offers or a solved problem give people a reason to click.

• Mobile

  Over 60% of email is read on mobile. Small links and broken layouts see 50% lower CTR there.

• Scannability

  Most people skim. Headers, bullet points and whitespace help them find the CTA.

• Number of CTAs

  Emails with one primary CTA convert 371% better than those with several competing ones.

• Write specific CTA copy

  Say what happens on click: “Download your free guide”, “Start your 14-day free trial”, “Get 20% off today only”. Not “Click here” or “Learn more”.

• Make the button stand out

  Use a contrasting color, at least 44×44px to tap, whitespace around it, and live text rather than an image. Repeat it at the bottom of long emails.

• Give each email one goal

  Competing CTAs reduce total clicks. Point readers at one action.

• Personalize the content

  Go beyond “Hi Name” with behavior, purchase history or preferences. Personalized CTAs see 202% higher CTR.

• Design for mobile

  Responsive, single column, concise copy, large tappable buttons instead of text links, and a CTA above the fold.

• Use real urgency

  “Sale ends tonight” or “Only 5 spots remaining” work when they are true. False urgency costs trust.

• Segment your audience

  Target by behavior, interests or demographics. Segmented campaigns see 3x the CTR of untargeted ones.

• Tease, don’t tell everything

  A product image, a stat or an excerpt creates curiosity. “Read the full article” beats a bare headline.

• A/B test your CTAs

  Test copy (“Get started” or “Start free trial”), color, placement, number of CTAs, and size and shape.

• Match the landing page

  If the email says 20% off, the page it opens should show 20% off, not the homepage.

How many CTAs an email needs, and where, depends on its length.

• Too many CTAs

  Competing actions confuse readers and lower total clicks. Pick one.

• Vague CTA copy

  “Click here” and “Learn more” say nothing. “Start 14-day trial” says exactly what they get.

• Image-only buttons

  Many clients block images by default, so the CTA disappears. Use HTML buttons with text.

• Small links

  Tiny text links are hard to tap on a phone. Use buttons of at least 44×44px.

• No reason to click

  People will not click if they do not know why. State the benefit before asking for the click.
